Roof Radiant Heat Barrier

Attics heat up when the sun s radiant energy heats the shingles and the heat is transferred to the interior attic space through the roofing materials via conduction.

Roof radiant heat barrier.

Radiant barrier foil insulation systems block radiant heat energy instead of absorbing it like fiberglass insulation. Our product is easy to handle and install. The list of uses includes crawl space radiant floor attic and walls. This basically allows for wood rot to continue and inspectors have a more difficult time finding areas of concern.

Reflectix insulation has over 20 energy saving applications for reflectix insulation has over 20 energy saving applications for around the home. Radiant barriers are utilized to reduce summer heat gain in attics. Your radiant barrier makes the roof deck sheathing invisible from the attic. Radiantguard radiant barrier foil insulation installed in an attics can reduce attic temperatures by up to 30 degrees when stapled with a staple gun to the underside of roof rafters by reflecting up to 97 of the radiant heat that strikes its surface thereby reducing heat transfer from the attic to living spaces resulting in lower utility bills.

The hot roof material then radiates its gained heat energy onto the cooler attic surfaces including the air ducts and the attic floor. A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. Also any water leak will fall onto the backside of the radiant barrier and roll down the slope until it reaches the eaves soffits. Underneath roofing materials or in the attic this keeps the attic airspace cooler during the summer.

But on the bright side. A radiant barrier works best when it is perpendicular to the radiant energy striking it. Increasing summer energy consumption and cooling costs. The temperature of the attic space increases and that heat is transferred to the building below.

This means radiant barrier can increase the life of the roof shingles. April 19 2019 posted in. Benefits of radiant barrier roof underlayment. This in turn prevents your house from heating up as much during the colder months this material will help prevent your home s heating from escaping through the attic and out the roof.

Installing a radiant barrier underneath the roof will cause the roof temperature to increase by a few degrees usually 2 10º.
